Atomic Barra Heavy Duty Timing Chain

Atomic Heavy-Duty Timing Chain – Ford DOHC 6-Cylinder
Engineered for high-performance Ford Barra and other DOHC 6-cylinder applications, the Atomic Heavy-Duty Timing Chain is a direct-fit upgrade over the factory single-row chain.

• Heavy-duty true roller Simplex design (8mm pitch)

• ~2x the tensile strength of the OEM chain

• Reinforced locking tabs with 50–60% thicker side plates

• Precision timing marks for hassle-free installation

• Genuine “A” stamped link to verify authenticity

Ideal for:

• High-RPM builds

• Engines with upgraded valve springs

• Performance street or drag racing applications
